LOCK.

Application filed March 26,1924. Serial No. 701,981.

To all whom it may concern:

Be it known that I, NORMAN B. HURD, a citizen of the UnitedStates of America, residing at New Britain, Connecticut, have invented a newand useful Lock, of which the following is aspecification.

My invention relates to a lock, particu larly, though not exclusively, adapted for clothes locker doors.

It is a general object. of my invention to provide a simple form of lock, which may be opened by key means and which may be locked by other manual means.

It is a more specific object to provide a lock for a locker door or the like in which the locking bolt is retracted by key means, and which may be released by other manual means. a

It is another object to provide a lock fol a dead bolt on a door, wherein the locking bolt may be retracted by key means and held in that position, and which may be released to lock the dead bolt by other manual means.

It is a further object to provide a highly simplified form of lock for a locker door or the like.

Briefly stated, a preferred form of myinvention includes what may be termed a locking plate controlling one or more dead bolts and manually operable by the usual handle on the outside'of a locker door or the like. The locking plate and its dead bolt or bolts are adapted to be held in locked position by my improved locking means, and the locking plate is further adapted to so unlatch or trip the locking bolt that the same may be moved forwardly to lock the locking plate and dead bolts in place. The improved locking bolt means isretracted by key-actuated means, and, when retracted,

is acted upon by a spring so as to latch the same in retracted position. The locking plate, when fully retracted, springs or trips the locking bolt so as to release it from its latched position, so that when the locking plate is moved to locked position the locking bolt moves forwardly to lock the locking plate in position. 6 a

In the drawings which show, for'illustrative purposes only, a preferred form of the invention Fig. 1 is a fragmentary view of the front of a locker door or the like, parts being broken away to illustrate features of my invention;

Fig. 2 is a perspective'view of my 1111- proved lock, the parts being relatively separated to better illustrate the construction;

Fig. 3 is a rear view of parts shown in Fig. 1;

, Fig. 4 is a side elevation of a so-called locking plate.

In said drawings, 5 indicates a portion of a locker door or the like abutting the usual jamb 6. A member, which I may term a locking plate 7, is pivoted to the door 5 and is operated by the usual handle 8 on the outside of the door. The plate 7 may carry a dead bolt 9 and, if desired, may also carry links 1011 for throwing other dead bolts, if such additional bolts are desired. Stop pins 1213 may be provided for limiting the oscillation of the locking plate 7 In the form shown the locking plate has a detent in the form of an upstanding flange 1 1, with an abrupt shoulder 15, for a purpose to be hereinafter described.

A lock case 16 is secured on the door, preferably at the rear thereof, and, in the form shown, has a guide or passageway 17 for a part of a locking bolt 18, which is adapted to slide thereon. One of the parts, in the present instance the lock case, may have a slot 19 for the reception of a pin 20 carried by the locking bolt 18 which, while pivoting the same, permits sliding movement betweenthe locking boltand the lock case. In the form shown a cylinder lock 21 is secured to the lock case, and the plug 22 extends into the passageway 17 and into a suitable recess or aperture 23 in the locking bolt 18. Means, such as a pin 24? carried by the plug 22, is adapted to fit in a part of the recess and acts against the surface 25 for retracting the locking bolt when the plug is actuated by means of a key from the outside of the door.

The forward end 26 of the locking bolt, and the part constituting the locking means proper, is offset relatively to the main plate 18 thereof. A guide notch 27 is provided in one side of the offset connecting portion, and at the opposite side there is a second guide notch 28. At the rear of the forward portion 26 there may be a lug 29 at one side tor the reception or one end of a coil spring 30. The lock case in the present form is provided with a pocket 31, for the reception of part of the end 26 of locking bolt and part of the ofi'set connecting portion. The edges 32-33 of the plate forming a part of the passageway 1? act as guides and extend into the guide slots 27-28 on the looking bolt. One side of this plate is cut back as at 34, so as to leave a sharp shoulder 35 to act as a latch for the locking bolt, as will be later described. The spring 30, in the form shown, fits in the pocket 31 and 1s suitably confined in a recess therein.

When the parts are assembled the main plate portion of the locking bolt 18 rests upon and slides in the passage 17, and the pin in the slot 19 pivotallysupports the locking plate on the lock casing. As has been stated above, the guideways 32-33 extend into the notches 2728 and confine the locking bolt. The extent of slidin movement is limited by the pin 20 anc corresponding slot 1%) and also, in the form shown, by the plug Y22 and the corresponding recess 23 in the locking bolt.

When the parts are in the full-line pos1 tion shown in Fig. 1, the dead bolt mechanism is locked and a keymay be inserted in the plug 22, and when the latter is rotated the pin 24, acting against the surface 25 of the locking bolt, serves to retract the latter. When the locking bolt 18 has been retracted to substantially its rear limit, the spring 30, which, as will be observed, is at one side of the locking bolt, serves to bias the latter toward the right as viewed in Fig. 2, and upwardly as viewed in Fig. 1, so as to cause the shoulder on the lock case to engage behind a part of the offset portion of the locking bolt adjacent the notch 27 and thereby latch the same in retracted position. The retracted latched position is shown in dot and dash lines in Fig. 1. lhe spring then serves not only to bias the locking bolt over, so as to latch the same, but also serves to i'orce the locking bolt outwardly when said locking bolt is released. As soon as the locking bolt is latched in retracted position the plug 22 may be rotated back and the key removed. \Vith the locking bolt retracted and biased and latched in the retracted position (dot and dash lines), it will then be possible to rotate the handle 8 counterclockwise sufi iciently to withdraw the dead bolt or bolts, so as to permit the door to be opened without disturbing the then retracted locking bolt 18. An extreme counterclockwise movement will cause the projection or flange let to act on the shoulder 36 on the extreme forward end of the locking bolt 18. so as to dislodge the latter from its latched position, so that it will spring forward slightly and stand in such a position that when the plate 7 is turned so as to again lock the door by means of the dead bolt or bolts, the locking bolt may then automati- -ally spring forward and thereby lock the dead bolt mechanism.

It will thus be seen that when a door is equipped with locking means as herein described, it is possible to unlock the door by means of a key, which may then be withdrawn. It is not necessary to have the key when it is desired to again lock the door, since, by an extreme counterclockwise movement of the handle 8, the locking plate is unlatched and held in readiness to move forardly when the plate '7 is rotated to lock the dead bolts and when the dead bolts are thrown into locking position by the locking plate the latter and the dead bolts, are securely locked in position by means of the forward end 26 ot' the locking bolt engaging behind the detent or shoulder 15'.

While one preferred form of the invention has been described in detail, I do not wish to be limited to the form shown, since the same is but illustrative and many changes may be made within the scope of the invention as defined in the appended claims.
